This is a base class for creating operators with branching functionality, similarly to BranchPythonOperator.
Users should subclass this operator and implement the function choose_branch(self, context). This should run whatever business logic is needed to determine the branch, and return either the task_id for a single task (as a str) or a list of task_ids.
The operator will continue with the returned task_id(s), and all other tasks directly downstream of this operator will be skipped.
Subclasses should implement this, running whatever logic is necessary to choose a branch and returning a task_id or list of task_ids.
context (dict) – Context dictionary as passed to execute()
